The BMW M4 CSL is a special edition that takes the M4 to the next level, following in the footsteps of the iconic M3 CSL and M4 GTS. With 40 more horsepower than the M4 Competition, the M4 CSL delivers enhanced performance thanks to aggressive suspension tuning, carbon-ceramic brakes, ultra-high-performance tires, and a 240-pound weight reduction. Limited to just 1,000 units worldwide and priced at $139,900, it offers a track-focused experience with even more precision and power. The M4 CSL is a rare, high-performance masterpiece, offering a significant step up in both performance and exclusivity compared to the standard M4 Competition.
